There is a dictionary-addition request flow. Submissions are reviewed for proper-noun / variant / inappropriate language before adding.

How strong is the CPU?

Easy is for beginners. Hard and Chaos are rating-linked and play seriously. Try Easy first to learn the per-turn conditions.

Is ending in 'n' always a loss?

In normal rounds, yes. In the final round, 'n-finish' is a major bonus — a comeback move.

The rules themselves are simple, but the dictionary contains adult vocabulary. There is an age gate; parental supervision recommended for younger players.

A note from the developer

The fun is when condition rules suddenly turn shiritori into a fighting game. Trying to answer in ten seconds with a 590k-word dictionary breathing down your neck — that panic is the whole point.
